Abstract

To cite this version:Rim Alrifai, Virginie Coda, Andon Rangelov, Germano Montemezzani. Broadband integrated polarization beam splitting based on anisotropic adiabatic transfer of light.A concept for the realization of waveguide-based polarization beam splitters working over a wide spectral range is presented. The adiabatically evolving three-waveguide system is inspired by the quantum-mechanical stimulated Raman adiabatic passage process and involves waveguides with an anisotropic refractive index contrast. It is shown that an index contrast ratio of 5 is sufficient to obtain excellent efficiency and output polarization purity over a spectral range approximately equal to 350 nm centered at a wavelength of 1550 nm. The center wavelength can be easily modified by tuning the parameters of the waveguides.

Long-distance adiabatic wireless energy transfer via multiple coils coupling

“…Recently, two coils coupling [19] and three coils coupling [20] propose an adiabatic technique to enhance the transfer efficiency, comparing with exact resonance method. The adiabatic following is a famous coherent quantum control technique, which is widely used in quantum system and classical systems, such that the quantum state controlling [14], quantum manybody processing [15], optical waveguide coupler [16], graphene surface plasmon polaritons (SPPs) coupler and terahertz SPPs coupler [17,18].…”

Ultrabroadband beam splitting in a dissipative system of three waveguides

“…Specifically, optical analogous to quantum mechanical adiabatic processes, such as STImulated Raman Adiabatic Passage (STIRAP) [4][5][6] have attracted much attention in this context. These quantumlike implementations for achromatic guided-wave beam splitting include the use of the so called fractional STI-RAP process [7], the multiple beam splitting in a non planar configuration reminiscent of tripod STIRAP [8], 1to-n multiple beam splitting exploiting the robust evolution of the adiabatic transfer state in specifically evolving planar arrangement of multiple waveguides [9], polarizing beam splitters in adiabatic systems of three anisotropic waveguides [10], the analogous to the two-state STIRAP process in gradually detuned waveguide pairs [11], or other interesting light redistribution functionalities involving various detuned three waveguides configurations [12]. The above adiabatic beam splitting solutions require a slow evolution and therefore the total propagation distance cannot be shorter than a certain minimum * rim.alrifai@univ-lorraine.fr value.…”

One-step implementation of a deterministic SWAP gate via a shortcut to adiabatic passage

“…Adiabatic passage (AP), initially proposed to achieve efficient and robust population transfer between quantum states, has been widely explored and applied in quantum optics and integrated optics [1][2][3][4][5][6][7][8][9][10][11][12][13]. When carrying out classical analogs of the AP [14,15], the well-known STI-RAP and its variants were most investigated due to their advantages of being robust, simple, and efficient [16][17][18][19][20].…”
